Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A method for playing back content data including audio data and image data that are synchronously played back, the method comprising: controlling a display to display an image based on the image data; controlling an output of an audio based on the audio data; controlling the display to suspend displaying of the image when a first operation is detected while the image is displayed; and controlling the display to display information related to the audio when a second operation is detected while the displaying of the image is suspended, wherein the output of the audio is maintained regardless of whether the first operation is detected.
A method for playing back synchronized audio and image data involves displaying an image based on image data, outputting audio based on audio data, and suspending the image display when a "first operation" is detected while the image is shown. When a "second operation" is detected while the image display is suspended, information related to the audio is displayed. The audio output continues uninterrupted, regardless of the "first operation". This enables control over the visual display without affecting the ongoing audio playback.
2. The method according to claim 1 , further comprising: controlling the display to temporarily display the image when the second operation is detected while the displaying of the image is suspended.
The playback method described in claim 1 further includes temporarily displaying the image again when the "second operation" (the operation that triggers displaying audio-related information while the image display is suspended) is detected while the image display is suspended. This allows the user to briefly view the image content before or after viewing audio information.
3. The method according to claim 1 , further comprising: in response to detecting the first operation, entering a state of not accepting inputs until a hold release operation is detected; and controlling the display to restart the displaying of the image when the hold release operation is detected.
The playback method described in claim 1 includes, upon detecting the "first operation" (which suspends the image display), entering a state where no further inputs are accepted until a "hold release operation" is detected. When the "hold release operation" is detected, the image display restarts. This implements a hold function, preventing accidental input while allowing uninterrupted audio playback.
4. The method according to claim 1 , further comprising: in response to detecting the first operation, entering a state of not accepting inputs until a hold release operation is detected; and controlling the display to restart the displaying of the image when a third operation is detected after the hold release operation is detected.
The playback method described in claim 1 includes, upon detecting the "first operation" (which suspends the image display), entering a state where no further inputs are accepted until a "hold release operation" is detected. After the "hold release operation" is detected, the image display restarts only when a "third operation" is detected. This offers an additional layer of control, requiring both a hold release and another specific action to resume image display.
5. The method according to claim 1 , further comprising: detecting a volume control operation that controls a volume of the output of the audio; and in response to detecting the first operation, entering a state of not accepting inputs, wherein the volume control operation is effective while the state of not accepting inputs is set.
The playback method described in claim 1 further includes detecting a volume control operation that adjusts the audio volume. When the "first operation" (which suspends the image display) is detected, the method enters a state where most inputs are ignored, but the volume control operation remains active. This ensures that the user can always adjust the audio volume, even when the device is in a hold state that disables other functions.
6. The method according to claim 5 , further comprising: receiving the volume control operation from a volume operating portion.
The playback method described in claim 5 includes receiving the volume control operation from a dedicated volume operating portion of the device. This emphasizes the presence of a physical volume control.
7. The method according to claim 6 , wherein the step of receiving the volume control operation comprises: receiving the volume control operation from the volume operating portion that is positioned at a first side face of a playback apparatus.
The playback method described in claim 6 specifies that the volume operating portion, from which the volume control operation is received, is positioned on a first side face of the playback apparatus. This describes a physical layout of the device.
8. The method according to claim 7 , further comprising: receiving the first operation from a hold operating portion, wherein the hold operating portion is positioned at a second side face of the playback apparatus different from the first side face.
The playback method described in claim 7 further specifies that the "first operation" (which suspends the image display and activates the input hold) is received from a hold operating portion positioned on a second side face of the playback apparatus, different from the first side face where the volume control is located. This clarifies the physical separation of the hold and volume controls.
9. The method according to claim 1 , further comprising: receiving the first operation from a hold operating portion, wherein the hold operating portion is positioned at a second side face of a playback apparatus.
The playback method described in claim 1 receives the "first operation" (which suspends the image display) from a hold operating portion positioned on a side face of the playback apparatus. This specifies a physical hold button.
10. The method according to claim 9 , further comprising: receiving a volume control operation from a volume operating portion, wherein the volume operating portion is positioned at a first side face of the playback apparatus different from the second side face.
The playback method described in claim 9 also receives a volume control operation from a volume operating portion located on a different side face of the playback apparatus than the hold operating portion. This describes distinct physical controls on different sides of the device.
11. The method according to claim 10 , further comprising: detecting the volume control operation that controls a volume of the output of the audio; and in response to detecting the first operation, entering a state of not accepting inputs, wherein the volume control operation is effective while the state of not accepting inputs is set.
The playback method described in claim 10 includes detecting a volume control operation that adjusts the audio volume. When the "first operation" (received from the hold operating portion) is detected, the method enters a state where most inputs are ignored, but the volume control operation remains active. This ensures that the volume can be adjusted even when the device is in a hold state.
12. The method according to claim 9 , further comprising: outputting the audio via a sound output portion, which is positioned at a first side face of the playback apparatus different from the second side face.
The playback method described in claim 9 includes outputting the audio via a sound output portion (e.g. a speaker) which is positioned on a different side face of the playback apparatus than the hold operating portion. This describes a specific physical arrangement of device features.
13. The method according to claim 1 , wherein the image is one of a still image, a moving image, or an image that indicates a playback status of the content data.
